This has specifically come up before in the form of “informal complaints” against yarnd because of the way it permanently stores and archives Twts, so even if you decide you changed your mind, or deleted that line out of your feed, if my pod or @xuu@txt.sour.is or @abucci@anthony.buc.ci or @eldersnake@we.loveprivacy.club (or any other handful of pods still around?) saw the Twt, it’d be permanently archived.
